The invention relates to novel modified
phenol-
formaldehyde resin, and preparation of modified
phenol-
formaldehyde /
epoxy resin anticorrosion
coating by utilization of the modified
phenol-
formaldehyde resin and
epoxy resin. Aiming at characteristics of traditional phenol-formaldehyde resin raw materials, high
toxicity, high volatility, high
irritation, and the like of formaldehyde, alpha, beta-furylacrolein which is high in
boiling point, low in volatility and low in
toxicity in place of formaldehyde is adopted to synthesize the modified phenol-formaldehyde resin with phenol, a
furan ring and a flexible
side chain are introduced into the modified phenol-formaldehyde resin,
furan resin is formed and
system brittleness is improved. The modified phenol-formaldehyde resin can be widely applied to the fields of plastic,
glass fiber reinforced plastic, amine mud, amine adhesives,
coating and the like. The modified phenol-formaldehyde /
epoxy resin anticorrosion
coating is prepared from the modified phenol-formaldehyde resin and the epoxy resin, has excellent properties of the epoxy resin and the
furan resin, such as
high adhesion force,
acid resistance, alkali resistance, resistance to high temperature and
ageing resistance, and can be used as coating for boats, oil tanks, pipes, and other structural objects.
